Also known as PE jaw crusher Jaw Crusher, jaw crusher, jaw crusher broken coarse and fine sub-two. First widely used in road construction, later used in mining. With crushing ratio, even granularity, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. Broken no more than 320 MPa compressive strength of various materials, the feed particle size of 125mm ~ 1020mm, primary and secondary crushing device of choice. In Section E Crusher major advantages of similar products from home and abroad, for the development of energy efficient equipment in one crushing, the major small jaw crusher series, sand and gravel as the main product, from design and production capabilities in terms of sales, in leading position. pe series jaw crusher is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry and many other sectors.
pe Jaw crusher works
PE series jaw crusher to squeeze-type dynamic song way. Motor-driven belt and pulley, through the eccentric shaft movable jaw up and down movement, rises when moving jaw toggle plate and moving jaw angle between the larger, thus promoting the moving jaw plate close to the fixed jaw, with the same time the material is crushed or split broken, broken to achieve the purpose; When the movable jaw down, the angle between toggle plate and moving jaw becomes small, movable jaw plate in the bar, under the action of the spring, leave the fixed jaw plate, this time under the broken material from the crushing chamber discharge port . When the pressure rises above the material’s strength can bear, that is where the breakage occurred. On the contrary, when the movable jaw to leave the fixed jaw swing in the opposite direction, the downward movement of the material is by weight. Movable jaw of each cyclical movement of materials by a crushing effect, to get some distance from the next row. After several cycles, the material begins to be broken discharge opening from the plane.
Pe Jaw crusher run cycle
Large stones will break into small stone in the process, often referred to as the first primary crusher crusher. The most common and most robust crusher is jaw crusher. In the feed to the jaw crusher, the material from the top of the entrance with a broken jaw tooth cavity. Jaw teeth with a strong force to the top of the material parietal, will the broken into smaller stones. Support the jaw tooth movement is an eccentric shaft, the shaft through the body structure. Eccentric exercise is usually fixed at both ends of the flywheel shaft produced. Flywheel and eccentric bearings are often used to support spherical roller bearings, bearing more demanding work environment. Bearings must withstand tremendous impact load, abrasive and high temperature water. Nevertheless, broken jaw still very reliable work, which is to ensure that the key to productivity.
Pe Jaw crusher structure overview
Jaw Crusher mainly by the body, movable jaw, safety device, adjusting device and parts.
First, the body: the body of the jaw crusher is the main component rack, the rack into the rack and the casting of carbon steel welded carbon steel frame two, the customer choose. In order to prevent serious wear rack wall, broken in body cavity on the left side of fixed jaw plate with side and, according to wear at any time.
Second, the rotating body: the moving jaw, eccentric shafts, bearings, pulleys and other several parts, the jaw crusher drive and resilience of the main parts.
1, the moving jaw using 35 # steel, processed modulated treatment. In order to improve efficiency and protect the movable jaw crusher, crushing chamber with optimal design at the jaw, according to wear, can be replaced at any time.
2, the eccentric shaft made of high quality 45 # steel, cars, and after quenching and tempering treatment after processing.
3, bearing a double row radial spherical roller bearings, with a fine, great endurance, durability, long life characteristics.
4, sub-activities jaw jaw plate and fixed jaw two, in order to improve the efficiency of crushing, jaw tooth surface using the optimized design, materials used ZGMn13, high hardness, impact resistance, wear characteristics.
Third, the adjustment device: Jaw Crusher company has raised a long adjustment device and ejector wedge type gasket type two structures, the device is used to adjust the size of the nesting population, control the jaw crusher discharge size , makes the product more uniform particle size, adjust the device convenient and flexible, to realize stepless adjustment.
